This is generally viewed unfavorably, I believe.

None of your characters are supposed to know any of your others, nor can they "be related" to any of them. While you could say that this is an entirely new character that just happens to have the same name as your past one, other players that have interacted with the previous Vandir will either be confused or carry over things from the first character.

If your character never gets above level 20 or never makes an impact on other characters this might not be as much of a problem and it might not be as terrible for you to re-roll with the same name. Don't take my word for it though, especially on the level I gave out as a cutoff.
